I want to place an ad in Seoul, preferably a subway ad (or any ad space available).
The thing is I don't know who or where to ask or contact to about it.
I am posting this hoping anyone could help me or redirect me where to ask for placing an ad/ renting an ad space in Seoul.
If by any chance you can tell me how, you may send me an email: firstname.lastname@example.org
thank you so much.
